Hi,
In bash:
Code:
$ value=malayalam
$ arr=($(for ((i=0;i<${#value};i++)) ; do echo ${value:$i:1} ; done))
$ echo ${arr[@]}
m a l a y a l a m
$ printf "%c\n" ${arr[@]}
m
a
l
a
y
a
l
a
m

Regards.

arr=($(for ((i=0;i<${#value};i++)) ; do echo ${value:$i:1} ; done)) : implicit array declaration
arr=($(for ((i=0;i<${#value};i++)) ; do echo ${value:$i:1} ; done)) : sub-shell.
arr=($(for ((i=0;i<${#value};i++)) ; do echo ${value:$i:1} ; done)) : loop for.
arr=($(for ((i=0;i<${#value};i++)) ; do echo ${value:$i:1} ; done)) : number of characters in $value.
arr=($(for ((i=0;i<${#value};i++)) ; do echo ${value:$i:1} ; done)): Expansion to a max of 1 character of variable value, from offset $i.
Regards.
